' SNUBBED STORAGE BIN This is a Division of Application Ser. No. 74,933 filed July 15, 1968.

. BACKGROUND OF THE INVENTION FIELD or THE INVENTION This invention is classified in Class 248, Subclass292, Counterbalanced horizontal single joint adjustable supports."

SUMMARY OF THE INVENTION This invention pertains to a new and novel storage bin which comprises a removable snubbing pivot pin at position. But, while downward openingmovement is efficaciously snubbed, the bin may be closed or pivoted back to its original horizontal position with no appriciable resistance from-the snubber.

Likewise, the storage bin is quickly removable by mere inward pulling of knobs on the pivot pins for changing, cleaning, or repair of the storagebins.

Also is disclosed a quickly, retractable, and extendable snubbing pivot pin mechanism for forming a highly efficient pivot for incorporation with a storage bin, particularly one for aircraft passenger carry-on luggage, and for being mountedin a storage bin supporting structure, as in an aircraft passenger transport, adjacent the passengers.

Accordingly, the principal object of this invention is to provide a quickly removable pivotal structure that may be pivotally connected to a support structure with retractable pivot pins.'

A further object of this inventioni's to provide a quickly and easily removable pivotal structure for pivotally mounting on a support structure with means for snubbing the pivotal movement between the two structures.

Another main'object of this invention is to provide a storage bin that is quickly removable, pivotal, and snubbed in its pivotal movement about its pivotal mount.

Still another object of this invention is to provide a quickly removable, retractable, and snubbing pivot pin mechanism combined with a pivotal rigid structure for mounting in a cavity.

Other objects and various advantages of the disclosed quickly removable, pivotal, and snubbed, rigid structure apparent from the following detailed description, together with the accompanying drawings, submitted for purposes of illustration only and not intended to define the scope of the invention, reference being had for that purpose to the subjoined claims.

BRIEF DESCRIPTION OF THE FIGURES The drawings diagrammatically illustrate by way of example, not by way of limitation, one form of the invention wherein like reference numerals designate corresponding parts in the several views in which:

F IG. 1 is a side view, with parts in section, of the rear portion of .the new storage bin shown in horizontal position in solid lines and in lowered unloading position in broken lines; I

FIG. 2 is a sectional view taken of 22 on FIG. 1;

FIG. 3 is a side view of the snubber of FIG. 1, with parts in section; I

FIG. 4 is a sectional view taken at 4-4 on FIG. 1;

FIG. 5 is a sectional view taken at 55 on FIG. 1. 3

DESCRIPTION OF THE PREFERRED. I EMBODIMENT I FIG. 1 illustrated, with parts in section for clarity of disclosure, a side view of the rear portion of the new and novel quickly removable, pivotal, and snubbed storage bin 10.

- Pivotal 'bin 10, FIG. 1, comprises a storage bin 11 combined and mounted in a quickly retractable and snubbing pivot pin mechanism 12, one mechanism for 0 each side. While each part of the two mechanisms are identical, each mechanism is the enantiomorphic analogue of the other.

Each snubbing pivot pin mechanism 12, FIG. 1, comprises a snubber l3 pivotally connected at its upper end to the bin 11 with pivotal connection 14 and at its lower end to level 15 with pivot pin 16. A shaft or pivot pin 17 of pivot pin device 18, FIG. 5, is nonrotatably but axially slideable in lever 15. From there the shaft or pivot pin 17 protrudes into a recess 19 in wall 20 of the bin supporting structure. 1

SNUBBER PIVOTAL CONNECTION 14 Pivotal connection 14 FIGS.-1 and2, for connecting another 13, FIG. 1, to a side wall of the storage bin 11 comprises pivot pin or bolt 22, FIG. 2, passing through a hole in the upper end of a piston rod 26 of the snubber, through a flange 23, and retained with nut 24, the flange being secured to the bin wall with screws 25.

SN UBBER 13 Hydraulic snubber 13, FIGS, 1 and 3, comprises the piston rod 26, FIG. 3, actuatable by piston 27 slideable in cylinder 28. Piston rod 26' has a large orifice and passage 29 a.nd small orifice 30 for fluid to pass from one side of the piston to the other. A ball 1 1 is retained internally of piston 27 by pin 32, the ball plugging the large orifice and passage when the fluid slowly flows to the right as the snubber'is compressed and shortened, as viewed in FIG. 3, whereas fluid flow to the left is fast and friction free as the piston rod extends.

FIG. 4, a section taken at 4 4 on FIG. 1, illustrates the pivotal connection of the lower end or cylinder 28, FIG. 4, of the snubber 13 and the left end of lever 15, FIG. 1, the latter being pivotally connected with pin 16, FIG. 4, passing through both and retained with locking pin or key 33.

PIVOT PIN DEVICE 18 FIG. 5, a section at 5 5 on FIG. 1 illustrate on of two pivot pin devices 18 of the overall snubbing pivot pin mechanism. Pin device 18 comprises a compression spring 34 around an intermediate portion of pin device shaft or pivot pin 17 compressed between an annular ridge 35 on the shaft and a wall surface internally of flange 36. The outer portion of shaft or pivot pin 17 is rectangular shaped and to the left of the ridge 35, FIG. 5, protruding from the flange 36, through a rectangular hole 17 in the lever 15, and terminating in the recess 19 in the bin supporting structure wall 20. The inner or right end of shaft 17 or pivot pin is round beginning with the annular ridge and extends internally of the bin I to a round hole in the flange 36 and the shaft extends further therefrom the hole where a knob 38 is fixedly secured to the shaft inner end. Ridge 35, with its round 1 outer surface, slideably actuates in a cylindrical cavity in the flange 36 enclosing the spring 34. Suitable bolts 39 secure the flange 36 to a side wall of the bin 1 l.

Thus in operation of the pivot pin device 18, compression spring34 spring urges in an axial direction the square end of pivot pin 17 out of its flange 36, through lever 15, and into bin supporting structure wall 20, whereby while pivot pin 17 is prevented from rotating, the storage bin 11 and flange 36 may freely pivot and rotate about the pivot pin 17. Inward manual pulling of the knobs 38 of both pivot pin devices on each side of the storage bin compresses spring 34 to permit inward movement of the pivot pins 17, to the left in FIG. 5, a distance of slightly over the depth of the recess 19 of the supporting structure wall 20, whereby the storage bin may be easily and quickly removed for cleaning, changing, repair, etc.

OPERATION OF THE QUICKLY REMOVABLE, PIVOTAL, AND SNUBBED, STORAGE BIN With a snubbing pivot pin mechanism 12 attached to both sides of the storage bin 11 at the rear thereof and with release of latch (not shown) for supporting the front portion of the bin, the bin front portion immediately tends to drop down with all its weight to an accessible position for aircraft passengers, for example, to retrieve their belongings and/or store more luggage in the storage bin before raising it back to stored positron.

As the bin drops, pivots, or rotates counterclockwise about thepivot pin 17, FIG. 1,'which shaft is nonrotatably fitted in the supporting structure recess 19, the lever is held stationary relative to bin support structure 20, and the snubber 13 contracts as it pivots about pivot pin 16, when the bin pivotal connection 14 moves toward pin 16 as it rotates about pivot pin 17 to the broken line position illustrated in FIG. 1. Contraction of the snubber 13 is resisted as the piston 27, FIG. 3, moves to the left, the ball plugs the large orifice and passage 29, and fluid flows only through small orifice 30.

Then when the storage bin is emptied or refilled and raised back up to the normal horizontal position, the snubber is easily extended with negligiable resistance due to the snubber fluid passing through both the large orifice and passage and the smaller orifice in the piston as the snubber 13, FIG. 1, is actuated from the broken line position to the right to the solid line, horizontal position.

Thus it will be seen that the instant storage bin is quickly removable, pivotal, and snubbed in a manner which meets each of the objects set forth hereinbefore.

Having specifically described my invention, I do not desire to confine myself to the specific details of the 6 constructional example herein shown and described as it is apparent that various modifications may be resorted to without departing from the broad principles of the invention as indicated by the scope of the following claims.
